BOLANOS-PORTILLA, DIEGO  and  MONTES-ROJAS, CONSUELO. EVALUATING PROPAGATION METHODS Alocasia macrorrhiza IN THE MUNICIPALITY OF SAN PABLO, NARIÑO. Rev.Bio.Agro [online]. 2016, vol.14, n.1, pp.53-60. ISSN 1692-3561.  https://doi.org/10.18684/BSAA(14)53-60.

This study was conducted in the municipality of San Pablo (Nariño) in order to evaluate methods of propagation (Alocasia macrorrhiza) and determine the best for the production of planting material. Design completely randomized with 4 treatments and 4 replications was used. The treatments were: T1 disc stem, stem buds T2-, T3-T4 suckers and buds. The planting material was obtained in the municipal nursery in San Pablo (Nariño), where an area of approximately 400 m2 with bore he was, whose health and productive state was acceptable. The analysis of variance detected significant differences among treatments for the variable plant height, while for leaves / plant there was no difference between treatments. Duncan test allowed us to determine that the method of propagation of buds was the best performing achieving an average of 125,8 cm/plant. Upon study completion, the methods of the stem disc and tillers were lower growth which showed an average of 96,9 and 105,4 cm/plant, respectively. The number of leaves per plant is independent of propagation method used, no matter what method the production of leaf biomass used will be the same.
